Bug 363687

Application: kvpm (0.9.9)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was trying to reduce the size of a logical volume in a volume group. I had forgotten to unmount the file system. KVPM told me that I needed to unmount it then crashed.

-- Backtrace:
Application: kvpm (kvpm), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
